o.o awesome!!! I like the way you use light and shadow. My first look went to the red cloak to the woman in white and then to the window on the left side. By the way... the window looks pretty real, as if it's from a photography.
Quality contrast. The juxtaposition of high detail and almost sloppy lines adds an element of cerebral realism, in that our minds eyes, as we imagine things, we pay more attention to the subject of an image, rather than the edges, the periphery. The unity of these different stylistic elements adds 'being' and an almost tangible, life-like quality to your work.
